HIGH 8.8

Vertex Addons for Elementor <= 1.6.4 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Plugin Installation and Activation via 'afeb_activate_required_plugins'

EPSS Percentile
25th

The Vertex Addons for Elementor plugin for WordPress is vulnerable to Missing Authorization in all versions up to and including 1.6.4. This is due to improper authorization enforcement in the activate_required_plugins() function. Specifically, the current_user_can('install_plugins') capability check does not terminate execution when it fails โ€” it only sets an error message variable while allowing the plugin installation and activation code to execute. The error response is only sent after the installation and activation have already completed. This makes it possible for authenticated attackers, with Subscriber-level access and above, to install and activate arbitrary plugins from the WordPress.
